Consumes auto_hardware.joint_explore(). UI:
- Sweep-depth radio: two_stage / balanced (default) / coarse
- Run joint sweep button + spinner
- 4 metric cards: HW candidates, feasible joint, Pareto count,
best latency
- Panel 1 (Pareto scatter): latency vs hardware cost proxy, feasible
in grey, Pareto colored by PE count, dashed line connects Pareto in
cost order — this is the "optimal HW config for the model" plot
- Panel 2 (sensitivity bar chart): per-knob relative speedup when
doubled from the baseline. Green bars, sorted biggest first;
annotated with the baseline → doubled values. Answers "where to
invest next?"
- Panel 3 (table): sortable Pareto joint configs with parallelism +
HW spec columns (PE HBM, HBM BW, TFLOPs, PE↔PE, D2D, C2C)
- Load into sidebar: picks a Pareto row and syncs both the HW
selectboxes (Per-PE + Interconnect sub-tabs) AND the parallelism
sliders. Values only get loaded when the target is one of the
selectbox options; otherwise the sidebar keeps its current value.
Session-state cache under _hw_result keyed by (model, s_kv, mode, depth);
if any of these drift, a warning suggests refreshing.
Verified: app.py parses; auto_hardware smoke run on Llama 70B decode
128K in ~20s produces sensible HW co-design signal (HBM BW 33% speedup,
everything else <1.5%).
Next: verification across Qwen 3 8B, Mixtral 8x7B (Commit 6).
